Energy dissipater structure

Abstract

The invention discloses an energy dissipater structure which comprises a bottom side wall, wherein a curve inner side wall, a flip bucket and an overflow channel are connected onto the bottom side wall respectively; a curved-surface wall is formed at one end of the overflow channel, a slope is formed at the upper end of the other end of the overflow channel, an included angle between the slope and the overflow channel ranges from 30 degrees to 60 degrees, two force dissipation ridges are arranged and fixed on the overflow channel, and the bottoms of the force dissipation ridges are communicated and connected with the overflow channel which is arranged parallel to the flip bucket, the top end of the flip bucket is an inclined plane, and a drop ridge in a diffusion shape is formed. The energy dissipation effect of the energy dissipater structure is sufficient, energy can be dissipated through mutual functions of self-buffer, impact and the like of water flow, water flows slowly, the water surface is smooth and good in flexibility, a natural connecting function with downstream tail water can be formed, the problems about energy dissipation of water flow with large flow and larger tail water level range are solved, and damage and influence of construction on the ecological environment in an engineering area are reduced to a certain extent.

Description

technical field [0001] The invention relates to an energy dissipation and anti-scour facility, in particular to an energy dissipation structure. Background technique [0002] In modern water conservancy projects, it is usually necessary to consider the comprehensive utilization of ecological water replenishment requirements and domestic and industrial water supply requirements. In concrete barrage buildings, ecological water discharge pipes or water supply pipes are often arranged, and the design flow of water discharge pipes or water supply pipes is generally relatively small. Usually it is a few flows to dozens of flows, but the acting water head is relatively high, which can reach more than 50 meters. In this case, the downstream foundation or slope is required to have a high anti-scouring capacity. It dissipates energy. Among the existing energy dissipation methods, it is quite effective to dissipate energy by building the structure of the dam surface. The traditional d...

Problems solved by technology

Among the existing energy dissipation methods, it is quite effective to dissipate energy by building the structure of the dam surface. The traditional dam surface is often built with a smooth curved surface with a small roughness, and most of the energy of the discharged water is transported to the end of the dam surface Centralized underflow energy dissipation, but the stilling pool required for underflow energy dissipation is deep and long, and the energy dissipation and anti-scour facilities require a large amount of work and high cost
